TrueNat MTB Technology

Statement 1: TrueNat MTB technology is a new molecular test that can diagnose Tuberculosis in a short interval of one day.

Statement 2: TrueNat MTB technology uses a polymerase chain reaction to detect bacteria.

Statement 3: While sputum microscopy has only about 50% sensitivity, Truenat has been found to have higher sensitivity and specificity.

The correct option is C, which means that only statement 1 is incorrect.

Explanation:

TrueNat MTB technology is a new molecular test that can diagnose Tuberculosis. It is a point-of-care test that can detect TB bacteria in sputum samples. The technology uses a chip-based, battery-operated, portable device that can provide results within one day.

TrueNat MTB technology uses a nucleic acid amplification test (NAAT) technique, which is based on the polymerase chain reaction (PCR) method. This test is highly specific and can detect the presence of TB bacteria in sputum samples.

Sputum microscopy is a conventional method used for the diagnosis of TB, but it has limited sensitivity. On the other hand, TrueNat MTB technology has been found to have higher sensitivity and specificity than sputum microscopy.

In conclusion, statement 1 is incorrect as TrueNat MTB technology can diagnose TB in a short interval of one day, not a new molecular test. Statements 2 and 3 are correct as TrueNat MTB technology uses the PCR method to detect bacteria and has higher sensitivity and specificity than sputum microscopy.

Consider the following statements with reference to TrueNat MTB techno...
On 17th January 2020, the Government of India renamed its National T. B. Control Programme to National Tuberculosis Elimination Programme. Also, the WHO (World Health Organization) recently endorsed technology developed by Indian scientists to detect the disease called TrueNat MTB in terms of accuracy.
Truenat is developed by the Goa-based Molbio Diagnostics. The TrueNat test a new molecular test that can diagnose Tuberculosis in one hour. The test uses a polymerase chain reaction to detect bacteria. The device that conducts the test is battery-operated. So, statement 1 is not correct and statement 2 is correct.
It has "high diagnostic accuracy as an initial test to diagnose T.B. and to sequentially detect rifampicin resistance," says the WHO Communication. It will be used as an initial test, thus replacing sputum smear microscopy.
While sputum microscopy has only about 50% sensitivity, Truenat has been found to have higher sensitivity and specificity. According to WHO, the overall sensitivity of the Truenat MTB assay is 83% and specificity is 99%. In TruenatMTBPlus, which uses two targets to diagnose T.B. bacteria, the sensitivity increases to 89% and the specificity is 98%. So, statement 3 is correct.
Therefore, the answer is (c).
